A phallus-shaped, green, and rather unhappy monster in Markus Persson's most popular game, Minecraft. They are renowned for sneaking up on players and exploding, killing the player and sometimes destroying something a player has built. They are hard to notice until it's too late, since Creepers don't make any sound when they're walking. When they fet close to a player, however, they hiss and explode. Like other monsters in the game, they can't spawn unless it's in a dark enough area, like in a cave, or at night. Many players will rage-quit after being killed by one and will not play Minecraft again for weeks on end.

Player is killed by a Creeper.
"Fuck! I didn't even hear the thing! Screw this game!"

A person who does weird things, like stares at you while you sleep, or looks at you for hours through a window. usually a close friend or relative. you know right away if that person is a creeper or does creeper things. it is not hard to spot the creeper.

A type of creature often seen in the In Development game, Minecraft. Similar to a suicide bomber but this creature lures prey into its line of fire by frowning and looking generaly sad. People fooled by this act soon are blow to millions of tiny bits as the creeper explodes. The creeper earned its name for its ability to swiftly sneak up on an unsuspecting player and quickly kill them, destroy their construction, and leave them exposed to more powerful monsters.
